Metered dose inhalers (MDIs), dry powder inhalers (DPIs), and nebulizers are modes of aerosol drug delivery that are used to treat respiratory disorders (eg, asthma, obstructive lung disorders, cystic fibrosis, pulmonary arterial hypertension, infectious pulmonary disease).

Medical Alert. USES: This drug relaxes the smooth muscle in the lungs and dilates airways to improve breathing. It is used in the treatment of asthma, chronic bronchitis, and emphysema. The inhaler enables the drug to reach deep into the lungs for maximum benefit.

The most significant difference between a nebulizer and an inhaler is the ease of use. A nebulizer is designed to place medication directly into the lungs and needs little patient cooperation. This is vital because the lungs are the source of inflammation.

As with nearly everything that has advantages, aerosol delivery of drugs also has its disadvantages, including: Special equipment is often needed for its administration. Patients generally must be capable of taking deep, coordinated breaths.

Aerosol: A fine spray or mist. Medications in aerosol form can be administered via a nebulizer and inhaled.

Nebulizers and inhalers can be equally effective in many situations, but nebulizers are better in some instances. Nebulizers deliver a continuous mist of medication that you breathe for 10 to 15 minutes or longer. This allows you to breathe normally through your mouth during treatment.

ASTHMA NEBULIZER Inhaled corticosteroids help to reduce inflammation in the airways and reduce symptoms of breathlessness and chest tightness. Using a nebulizer to take your maintenance medication daily can help to prevent asthma symptoms from flaring up and asthma attacks from occurring.

The inhalers available for people with COPD help improve breathing by opening up the airways. Inhalers are often effective for rapid symptom relief and to minimize episodes of breathlessness. People typically inhale drugs known as bronchodilators to treat COPD symptoms.
